Problems with XY/Z

I’ve been continuing to work on XY and Z. To date, I’ve heard almostnothing from people using them. What problems have you had?What points in the documentation are unclear? Is anyone usingthem at all? – Tim

Haven’t had a chance to really exercise your new versions of XY and Z. Don’t expect to get to them for a couple of weeks.

I did try to download your new TEX stuff. First attempt was at 14400. Got 2,143,232 bytes of the latex_tar.gz file and then error’d out. Time was 1 hr 11 minutes. Wasn’t able to successfully download the 2 files following.

This morning I logged in at 9600 and was able to successfully download latex_tar.gz, tar and gzip using XY. Time for latex_tar.gz was 1 hr 13 minutes. Works out to about 5158 baud.

I’ve used xyz a few times…So far, I can’t recall any perticular problemsin the transfer part, alhough, I have noticed, that if frorked froma shell (S) in sterm, and you are at the bottem of the screen when youstart it, it will whipe out the transfer stats line when it finishes (ie. youneed to put in an extra CR or two to scroll the screen after it is done..)–Paul

Come to think of it there is a problem that is annoying me lately, butnot because of XY/Z. Using Sterm on Delphi, Delphi seems to send a code atone time or another (maybye going into mail) that the window interprets astransparent characters on. Then when I ESC-S to get a shell and “z;display 7″the file % update (wich I really like) writes over itself making it a garbledmess. How can this be avoided? I know it’s something Delphi sends me becauseIv’e ESC-S and fixed it with a display code and it creeps back again.

While we’re giving hints …. I think I mentioned it before, but I’vehad a little problem of losing the dload if I have screen pause turned on,and the screen pauses.. If you don’t already do anything with the OPTS,would it be a hindrance to _gs_opt, save it to restore on exit, then turnoff pause? I think it would be a help.

Is your modem not error-correcting? I wouldn’t use -G with a non-correctingmodem, but with E-C modems, I’ve been fairly successful with my local BBS.

I still tend to use ZModem most of the times, however.

BTW.. Last night I had a funny occurrence. I tried Z for the first timehere and dloaded a file. At the end, suddenly, Z started again (From themenu, it appeared to be only one file.. Anyway, the thing seemed to stickfor a while, I think I hit CTRL-C, then suddenly Delphi seemed to bereceiving my logon, Getting my Handle, then my password, of course respondingwith error messages.. Apparently Delphi was sending it to itself, becauseI use STerm, manually logging on. I first thought it was sending my capturebuffer, but my password was not even in that file, so I don’t know what wasgoing on.

Sounds like Delphi is sending you the sequence “ESC < " ($1B $3C) whichis the GFX code for setting transparent mode (needs a parameter: $00 isoff; probably any non-zero would be on).

This coincides with the VT52 sequence to set ANSI cursor mode. Perhaps youcan eliminate this by changing your terminal type in Delphi. (Sorry, Idon’t recall the Delphi commands for doing this — I usually traversethe Delphi maze by trial and error… or let InfoXpress do it for me .)

I think DEC Mail sends either ESC ( 0 or ESC ) 0 when entering mail. I don’tremeber what they are supposed to do, off hand, but I’ve got a VT102 manualat home if you really need to know. Anyway, try one of those to see if itdoes the same thing in a plain window.

Hummm, I’ve seen that too Ken, only not on this coco. But when I capturethe stuffs with a “vlt” script on my amiga, there sure is. It puts myamiga in the BOLD text mode, adding a pixel to the width of any vert linesin the character. I(‘m not sure that its supposed to, but then “vlt” issupposed to know all about vt-100/220 codes, or even tektronix stuffsas its used a the Stanford Linear Accelerator labs to make terminalsout of all their amiga’s. Nice proggy, docs could use some help tho.Cheers, Gene

Which windio are you using. I never had that happen with any terminal programI’ve tried unless I’m downloading something and the d/l craps out but Delphikeeps sending. I should ask which term program are you using?

You could either change your Delphi setting to a safe one (“Unknown”), orswitch to a terminal program that handles the sequences safely (that is,one that doesn’t pass the VT control sequences directly to the screen).Better yet, get one that does a good job of VT100 emulation, and changeyour Delphi terminal setting to VT100…

Same here, sometimes it doesn’t change back for me.

More than likely the problem is caused by the MM/1 not properly implementingone of the VT52/VT100 control codes or escape sequences. I do not knowwhat you can do about it unless you can find the offending string andhave the terminal program strip it. I do know one of the sequences setsthe keyboard to application mode.

Making this short because I am using a stupid version of Telnet thatsends control character garbage when I use a non alphabetic character.Sheesh.

Interesting. Never happened to me before.

Why in the world did they use ESC = for Bold switch? Seems to me theycould have used an extension to the ANSI color change sequence to speficybold — assuming Bold is not already defined in the PC ANSI sequence –and not have a problem when running true VT52/VT100 emulation. Oh well,such is life.

Greg, Would you pass this along to Boisy. He is caretaker of KWindows. If itis a bug, it will get on the bug fix report. If not, then mabey somethingcan be done to correct the problem in future release.

OK. I’ll have to check that out. Haven’t used sterm in a long time. Keptseveral versions so maybe I’ll try them all and see if I get the same effect.I just don’t remember that happening. As they say in the PC world, “….anundocuemented feature!”

I have had the Zmodem thinge happen to me many times. I have executed aZModem download using KTerm V2.1 and at the end of the download haveDelphi start another. After terminating the download, Delphi would try andstart another. I don’t think it is the ZModem on my end. KTerm uses aexternal ZModem routine. I have used the same routine with STerm. thentoo, it doesn’t always happen. I would say mabey 1 time out of 20 DelphiSessions. I have had this to happen on Delphi, finally get out of it,close Delphi, dail up another BBS, use the same ZModem with perfectresults.

Hi, John -

As you may have noted from one of my subsequent messages, this isn’t abug, but rather it is a function that has been included as part of the“CC3 Level2 Windows Compatibility”. As you know, K-Windows provides boththis compatibility and some (limited) VT100/220 support.

This seems a little like what happened to me. A second d/l seemed to beattempted.. But when I broke out of “z”, it I got to the “What do you wantto do” prompt.. Then my username appeared (“No such command” or whatever”)Then my password appeared..

Yeah, you get timeouts… I think this is when the lines get busy..However, after the first d/l, (the file seemed to be intact, unzipped withno errors), I decided to get the ghostscript forte.. Used “rz”, would getbunches of timeouts, but d/l’ed everything.

The above really seems weird. Don’t know if my computer sent a code to causethis or what.

Sorry, my mistake. It was sounding like they were going with VT52/VT100/ANSIemulation instead of the CoCo emulation codes. I guess they used a combinationof the two, which does make sense. Now let’s just hope nobody thinks I’m anassinine swine and beat me with a club.

Yeah. That ones on my list, too. (disabling screen pause). It’snot as big a problem with the newer version, since it doesn’t scrollthe display; it uses a rolling display like `xydown’ used. Nevertheless,I’ll try to get the screen pause fixed before the next release.(By the end of the month if all goes well.) – Tim Kinetlze

John, that chip is at $0e00280.bits 6 and 7 of the input port will always return 1. I have no more infothat that I can find at the moment, and this system is timing me out even whenI’m typing so I’ll have to check offline…
